may be designated as s cystoscope and is in tended to be used in cxamination' of parts of the body by: physicians and sur sons for treatment in diseases ofvarious variousparts of the; body which are not easily' accessible for such examination and treatment. 7 a

The device consists primarily Of a main body portion or sheatlri of "tubular. form provided at gone end. with a rounded cap for closing the same and-- also Ittith .fenestral openings opposite which is positioned a lamp for illumination, The circuit for this is supplied h an; insulated wire which is p 21.1 d ins. smai tube and which is in turn lacd-in sfslot the wall of the sheath.

' 9 other side oflthe circuit maybe formed by the sheath itself.'.; This method of placing the wire leadlinj slot leaves the tubular opening in the sheath; free and clear and also ace-for the sameJ-z-t-a' The fenestral ojierdngs in the sheath opposite sides of .t lam are oh relatively large size and allow the lig t to pass in every -86 directionfrom the lam 'Ihis-permits the" examination-lot all bit esurro'undin' parts of the hddy s.nd',;bythe of suite is re; ilectos, s vics r'i rearwardlyy-inay also be ob guinea r 40'?

' a At 1. shown the main body psi-titular? tubular sheath which is provided atone with a cap, such as 2. A lamp 3, is posi tioned at one end of the device having on 0 terminal, such as 4, connected to the cap and sheath and the other terminal connectedv through a sleeve 5 and collar 6 to a wire lead 7 which may bo'slaced in a tube 8 whichis; ,1 in a slot in the wall of the 7! tubular sheath 1. This is indicated b dot and dashTline extending lengthwise of] the sheath in Fig. 1 and terminatm in the connection indicated at 10. AsuitaEle nection, as indicated at 11, may-l he provided for connecting the circuit to the sheath 1 in order to complete the lamp circuit. Suitable valves, as indicated at 12, may be pro.-:

Ivided'if desired so that the device may beusedforinjecting liquids to the diseased pora5- tionj'of'the body under treatment;

Fenestral openings, whichare indicated v 13'and,14,'are provided on opposite sides of the tubular sheath and near one end thereof. Between these o enings on the interior of the sheath'is locate a trans arent shield tube 9. This tube is provided with a rounded or hemispherical inner end and is 0 on at the oposite end. The interior 0 the sheath is ored out and formed to correspond with the "exterior surface of the shield tube and so formed-seat or socket in which the same is held securely and reouires the use of very little or no cement to old the samelin placm As the cement and other simihir lnaterials which aroused to sccure'thc tube in place absorb the diseased and poisonous matter itv becomes very essential to do away with the uselof'any such material as far as it is p0sslhle, and this is accomplished in a very sim ple manner by a construction such as de-iscribed in my invention. The rounded inner end of this tube also possesses many advan ta es and is easily keptclaim;

' t will be seentllat the shield tube 9 110 opening on the concave side extends down cupiespnly the forward portions of the fenestral openings, leaving the rear portions of these openings entirely unobstructed; and, since these openings lead into the bore of the instrument, it folTows that the same openings serve to permit the rays from the lamp to illumine the portions of the body being examined and also to furnish observation apertures for the operator. Through, these openings, too, pass such liquids as may be admitted through valves 12.

The lamp S-is provided with. a metallic sleeve 5 which fits closely in a collar 6 on the interior of the shield tube 9. This supports the lamp securely in place and the same is protected against breakage and contact with the body by means of the shield tube.

' The fenestral o enings 13 and 14 are so positioned with re ation to the lamp that the 'ght may emerge therefrom and allow the inspection of objects in line with the axis of the sheath. When the sheath is bent at one end at an angle, as shown'in Fig. 1., the light from the opening 13 will illuminate objects lying to the rear thereof and by using suitable reflectors the same may be viewed with equal facility. This arrangement of a single long opening extending longitudinally on either side of the lamp provides a very wide range of vision both to the front and the rear. 1n the angular construction shown in Fig. 1, the

into the main portion of the sheath.

The modification shown in Fig. 5, illustrates a straight construction of sheath.

Various modifications may be made in the details of construction herein shown and described and many apparently widely different embodiments of my invention may be made Without departing from the sco 0 thereof. It is intended therefore that the (lescri tion and drawing herein be construed as an 1 lustration merely and not in a limiting sense.

What I claim is:
